K-ESS2-1 Use and share observations of local weather conditions to describe patterns over time.
Clarification Statement: Examples of qualitative observations could include descriptions of the weather (such as sunny, cloudy, rainy, and warm); examples of quantitative observations could include numbers of sunny, windy, and rainy days in a month. Examples of patterns could include that it is usually cooler in the morning than in the afternoon and the number of sunny days versus cloudy days in different months.
Assessment Boundary: Assessment of quantitative observations limited to whole numbers and relative measures such as warmer/cooler.
This resource is explicitly designed to build towards this performance expectation.
Comments about Including the Performance Expectation
In this lesson, students keep daily records of temperature, precipitation, and wind. They plot their data and look for patterns of ups and downs without getting deeply into the nature of climate. To fully meet the Performance Expectation, this should be taught in at least two different seasons so that students have first-hand experience with weather patterns.
